i hate math and i am confused

is it wrong

or right????????????

[emarcos]

@dorkdiaries28 The answer is correct. What is confusing? Changing the fractions or subtracting them?

it's really 1 7/9 bums

[emarcos]

@PricelessBehavior No, the answer is correct. If you round it, 3 4/9 is about 3 1/2. And 2 2/3 is just more than 2 1/2. So, using our rough rounding... 3 1/2 - 2 1/2 is 1 and 7/9 is about 1.

@79holdentorana That's certainly a stupid comment. Thanks for watching! :)

@SuperHappyface13 The answer is in simplest form. 7/9.

God I hate math. What a bunch of tedious bullshit that I will never apply in everyday life. But yet, I have to learn it.

@ACutePanda6 That's the only way..if your too lazy to multiply one number and add it to it then simplify then your just a lazo.
